Abstract: Embodiments of the present disclosure generally relate to livestreaming methods and systems, and more particularly to whiteboard presentation systems that can be used in a livestreaming or video conferencing environment. In some embodiments, the whiteboard presentation system is configured to perform one or more processing operations, such as capture images on a whiteboard, perform image processing routines on the captured images, and transmit processed images as a video feed to one or more remote users, such as people or locations attending a video conference. The image processing routines can include one or more operations such as image denoising, contrast enhancement, color reconstruction, segmentation of a presenter, and image reconstruction.

Abstract: A system and method for providing video conferencing are described herein. Original video streams from one or more cameras are sampled to form downscaled versions of the video stream. The downscaled version is analyzed to find regions of interest and generate metadata describing aspects of the regions of interest, including a region that includes a preferred speaker and the best view of each participant present together in the video conference. Cropping instructions are generated from the metadata, and portions of the original video stream are removed to form a set of presentation views for each participant, including the preferred speaker. The set of presentation views is stitched together to form a composite display for each participant viewing the stream remotely.

Abstract: In one or more embodiments a computer implemented method includes generating, by a sensor, a video stream that comprises a series of frames that include a plurality of objects positioned within an environment, determining the objects captured within at least one frame of the video stream, determining one or more croppings for each of the objects in the at least one frame, determining a ranking of the one or more croppings based on a determined total combined loss value for each the one or more croppings, determining each subtiling combination for each of the one or more croppings, each subtiling combination comprising at least one subtile that includes at least one object; determining a total subtiling penalty value (TSPV) for each subtiling combination, and determining a preferred subtiled combination based on the total combined loss value of each the one or more croppings and the TSPV of each subtiling combination.

Abstract: A method of training a machine learning model includes training a primary part of a composite neural network to identify a primary segment of objects in a training image, freezing the primary part of the composite neural network after training the primary part of the composite neural network, and after freezing the primary part of the composite neural network, training, using activations of the primary part of the composite neural network, a secondary part of the composite neural network to identify a first subsegment of objects or a feature of the first subsegment of objects in the training image. The first subsegment of objects is a subset of the primary segment of objects.

Abstract: Embodiments herein generally relate to video-conferencing systems, and more particularly a method and system for optimally grouping and auto-cropping a field of view (FOV) of the video-conferencing system based on predefined preferences, such as preferences determined by a user. Generally, embodiments of the disclosure provided herein include a video-conferencing system that is configured to update the presentation of participants within a video conference to regularly determine the optimal presentation of the participants at any given moment in time based on predetermined preferences, while mitigating defects and related unwanted distractions typically generated in the video conference presentation due to the changes provided in the updates. Embodiments of the disclosure allow the predetermined preferences to each be given an importance level rating so as to allow the presentation of the participants to be optimally provided without making unnecessary and/or distracting updates to the video conference presentation, and also help resolve conflicting or competing attributes of related preferences.

Abstract: The present disclosure generally provides for advanced single camera video conferencing systems and methods related thereto. The advanced single camera video conferencing system features a hybrid optical/digital camera, herein a camera device, having a controller that is configured to execute one or more of the methods set forth herein. In one embodiment, a method includes optically framing a first portion of a video conferencing environment to provide an actual field-of-view, digitally framing a second portion of the video conferencing environment to provide an apparent field-of-view that is encompassed within the actual field-of-view, generating a video stream of the apparent field-of-view, surveying the actual field-of-view to generate survey data, and detecting changes in the survey data over time. The method may be performed using a single camera device using a single image sensor.
